Manziel issued a statement saying, "The Spring League has provided me with a great opportunity to play ball again, and ultimately, that is all I want to do".
The Spring League will run from March 28-April 15 and consists of four teams largely made up of players with NFL experience.
Manziel hasn't played a football game since being cut by the Browns following the 2015 season.
Morata claims Mourinho advice made him a top player
But he has struggled since, scoring just two in his last 10 league games and attracting criticism for several wasteful performances in front of goal.
The 25-year-old spent just two seasons with the Cleveland Browns after being a first-round pick in 2014.
Not only will Mayfield be able to figure out what went wrong for Manziel on the field, but he'll be able to learn from his mistakes off of it.
Manziel recently appeared on Good Morning America, and opened up about a lot of things including his alcohol abuse and that he's being treated for bipolar disorder. I'll be joining @TheSpringLeague in Austin to get #ComebackSZN started! Can't wait to get back on the field and show National Football League scouts what I can do!
We won't have to wait long to see Manziel compete for the first time in years. I don't feel like I've wasted the prime years of my life.
Medical examiner, jurors break down in tears during girl's murder trial
Judge Mallory Cooper denied the mistrial motion. "Did you want to believe him?" prosecutor Mark Caliel asked. The jury will now hear evidence in the trial's penalty phase as it decides whether to sentence him to death.
But to get back in the NFL, a league full of second and third chances and short on competent quarterbacking, he also must show he can still rediscover at least some semblance of being the breathtaking playmaker he once was. "That's what I thought would make me happy and get out of that depression".
Manziel's comeback journey included an offer from the Canadian Football League's Hamilton Tiger-Cats, but a January 31 deadline for the sides to strike a deal passed without an agreement. But I still feel like I have the time to do it and make it happen.
For now, it's refreshing, and to those close to Manziel I would imagine a huge relief, to see Johnny Football looking human again, lest we forget the zombie-like state to which he'd spiraled a couple years ago.
"At the end of the day, I can't help that my wires are a little bit differently crossed than yours".
